What is the purpose of a blow-off valve?

A blow-off valve, also known as a bypass valve, releases excess boost pressure from the intake system when the throttle is closed. This prevents compressor surge, which can damage your turbocharger and reduce performance.

What does the 'No Weld Flange' mean?

The 'No Weld Flange' design means the valve can be installed onto your intercooler piping without requiring you to weld a specific flange onto the pipe. This makes installation easier, especially for custom setups where welding might not be feasible.

What boost pressure is the green spring designed for?

The green spring included with this valve is typically rated for boost pressures in the range of 15-20 PSI. If your application runs significantly higher or lower boost, you may need to purchase a different spring.
